1. The fluid resistance is small, and the full-bore ball valve almost no flow resistance.

2. The structure is simple, small volume and light weight.

3. Better Sealing. It has two sealing faces, and the sealing surface material of the ball valve is widely used in various plastics, and has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.

4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.

5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.

7. Wide range of applications, Size from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.

8. Since the ball valve is wiping during opening and closing, it can be used in a medium with suspended solid particles.
